[LLDB-MI] Add (gdb) prompt after =breakpoint-modified and =breakpoint-created.

[dawn]

Summary

This patch causes lldb-mi to print the (gdb) prompt after =breakpoint-modified and =breakpoint-created notifications. This makes it clear to the user and IDEs that lldb is done and ready for input.

[abidh]

Looks good.
